SPECIFICATION forming part of Letters Patent No. 404,531, dated June 4,1889.

Application filed January 19, 1889. Serial No. 296,943. (No model.)

To all whom it may concern.-

Be itknown that we, ANDREW GALE and EUCHER TREMBLAY, both citizens ofthe United States, and both residing in Ohicopee, Hampden county,Massachusetts, have made and invented certain new and usefulImprovements in Swivel-Flows, relating to the construction of thefoot-latch, standard, and lever connecting the foot-latch and jointer,and to the combination of the same parts with each other and with otherparts of the plow, the main objects thereof beingv to effect the turningand setting of the j ointer by the same motion and at the same time withthe footlatch; and, further, so to arrange the parts.

Fig. III, an end elevation of the jointer-pinion, the same and allsucceeding fi'gures being on a scale larger than the preceding; Fig. IV,a plan of the curved lever which connects the foot-latch and jointer;Fig. V, a side elevation of the'rear portion of the curved lever; Fig.VI, a plan of the lock in whose notches the arms of the foot-latchcatch; Fig. VII, a plan of Fig. VI inverted; Fig. VIII, a side elevationof Fig. VI; Fig. IX, an end elevation of Fig. VI; Fig. X, a

view of the foot-latch, showing an edge ele-- vation of the slottedprojection; Fig. XI, another view of the foot-latch, showing a plan ofthe slotted projection;

In our improved plow the point, landside, mold-board, beam, handles, andall other parts not hereinafter particularly described are made,constructed, and connected in any of the usual and well-known ways.

The foot-latch 1 is provided with the usual arms 2 2 2 and catches 3 S,and in addition we provide such latch with the central projection 4, inwhich we form the slot 5,the object of which is to provide means forcombining the latch and jointer, as hereinafter described.

. The standard 6 is made of about the same interior thickness as thelandside 7, but is provided or furnished on both sides, at front andrear, with moldings or projections 8 8',

. between which the handles 9 9 are held rig- On the rear of the idly bythe bolts 10 10. standard is formed or made fast the lug 11, projectingon either side, and to which is bolted and made fast theirregularly-shaped lock 12. This lock is provided on its under side withsix notches 13 13, in three of which the arms of the foot-latchalternately catch and are held. Below the foot-latch is the cylindricalrubber spring 14 and its cap 15, and the cap, spring, and foot-latch areheld to the lock 12 by bolt 16. The spring 14 gives or yieldssufficiently to allow the latch to be moved from one set of notches tothe other when the plow is turned from side to side. The front of thestandard is provided with a projection 17, in which is formed ahorizontal slot 18, in which slot is hinged, by means of bolt 19, theirregularly-shaped lever 20, terminating in front in the short rack 21and in the rear in pin 22. The lever is sufficiently curved around thehandles-and standard to give it the necessary lateral play without itscoming in contact with such handles or standard. In the rear the lever20 is connected with the foot-latch by the extension of pin 22 through;slot 5. Forward the lever 20 is connected with the jointer 25 by thepinion 23, made fast on jointer-arbor 24, the pinion 23 meshing into therack 21, and the length of lever 20 and the size of pinion 23 are-suchthat by the turning of the foot-latch from side to side, so as to lockand hold the mold-board, the jointer is at the same time and by the samemovement turned, set, and held in its proper place for use. From this itis obvious'that the construction of our improved plow is such that thehairdles 9 9 and beam 27 maybe entirely detached and removed withoutdisturbing or separating any other parts of the plow, and to accomplishthis one of the objects of our invention.

WVe prefer to make the beam 27 of wood, for lightness; but it may bemade of any other suitable material.

Having thusdescribed our improvements, what we claim as our inventionis- 1. In combination with the standard and 3. The foot-latch having theslotted plate mold-board of a reversible plow, the foot- 4 and itsactuating mechanism upon the latch having slotted plate 4, the slottedstandplow-standard, lever 20, having rack 21, and ard projection 17, thepivoted lever 20, pinion pin 22, in combination with the jointer 25, ro-15 5 23, and the jointer-arbor, substantially as tating stem 24, andpinion 23, substantially shown and described. as shown and described.

2. The combination, with the reversible ANDREW GALE. mold-board, of theplow-standard having the EUCHER TREMBLAY. lug 11, the lock-plate 12, thefoot-latch 1, the Vitnesses:

:0 spring 14, and bolt 16, substantially as shown SIDNEY SANDERS,

and described. ELLEN S. ROBERTS.
